I don't understand this, but when I have "Ancient Spirit Water" at my Upper Action Bar (as Mage/Warden) and I don't have the potion in my backpack. Then when I SWAP to Mage/Warrior and I SWAP back to Mage/Warden, then where I had my "Ancient Spirit Water" potion there is now what I had at my Mage/Warrior Upper Action Bar. It's like when you don't have the certain item in your backpack it just goes away and gets replaced with the other classes skill/pot. Same happens when I have a skill from a Title in my action bar, and I'm not wearing the titel which gives me the "titel-skill". As long as I stay at the same prim/sec class it don't disappear (or log out). It first disappear when I SWAP class
